T0 all whom it may concern Be it known that I, DON L. CLEMENT, a

citizen of the United Ei-mtes, residing at Evangeline, in parish of Acadia and of J ismim, we 1&1, I I Si f i i on he *n ntco ceram new and useful improvements inTrsction:

Wheel and I do declai I the following to he a ll, hlezir, eXace description of the invention, such will enable others skilled in the art to which it appertains to make and use the same.

Thisinvention relates to carriages and wagons, and more especially to traction iwigons, engines machines and the object of the some is $0 produce an improved tractor Wheel b means :01 preventing it from slippiin; soil.

This object is providing thcriin of the wh' his around c cmnifercnce vii-l? r-l form of :4 p ping inechani. n1 constituting the or my invention, all as hereinafter more 1 ly described and claimed, and as shown the drawings wherein--- Figiire 1 is a side elevation of a traction Wheel embodying my invenoiam; Fig. 2 is a detail plan View of a portion of the rim of the Wheel; Fig. 3 is a sectional perspective JiQW of a portion of the rim showing the mii'i-slippin' inccl'ianism; Fig. 4 a longiiudiinil through the parts shown in Fig. 3; Fig. 5 is a i'ransvcrie section taken on line 5-5 of Fig.4; Fig. (5

Secured to the inner side or" the rim or preferably cost integral therewith zit ihc time it made is a log 1 COnSiil'lli-ii'lf' casing wherein at 2 is pivoted a sum ,1 Aug 3 which pro ects radially mental v through an opening :2 in the rim and takes the place oi one of the rigid lugs as shown. The opening l is of suilicient Width to permil, the protruding end of the lug 3 tossing a liitlc, with tlieiresult that, if the Wheel said end. wiilmove forward as clei'ncni,

Jolt is drawn against foo tension of i s Lg so as to disengage tip from Q. i ye 25, and at this time Weigh; will he in such position that us scent will tend to straighte out the oggle lever comprised by the lin 17 and 1%, and igh the slot 12 rim 1% to reliably the earth and prevent further slipping of the Wllfil In the. act of straightening out said toggle, the cor? trel gai'vot 19 passes a direct line between r front end with slides C W To above.

wheel continues to rotate and the weight is thrown upon the protruding end of the tongue 21, the latter cannot, be forced 111- Ward because the inner end of the link 18 rests against the bracket 13 and prevents the toggle from opening. When, however, this portion of the device has passed. the lower side of the wheel and commences to ascend-on the rear side, the weight finally falls over its pivot 14 and moves its enlarge ment 17 toward the hub, and this action carries the pivot 19 with it so that the toggle lever is actuated to retract the tongue 21 until the eye 25 of the latter comes in alinement with the bolt 7, when the spring thereof will project its tip into such eye and hold the parts in this position for renewed actionas the wheel rotates the second time. However, the spring may be made suiiiciently strong to prevent this action ofparts unless the wheel slips more than it does ordinarily on the road usually traveled by traction machines. means than a weight might be emplo ed for projecting the tongue, but 1 pre er the weight and the toggle lever as described point 20, as shown in dotted lines at theright of Fig. 1, it is obvious that the weight cannot fall to a position where the toggle lever will project the tongue 21, eventhough the bolt 7 be retracted so that its tip disengages the eye 25. At any time when this device is tooperate, the screw 30 is retracted or removed. I would by preference make all parts of metal, and there I are four or more of these devices disposed around the periphery of an ordinary traction wheel so. that no considerable portion of the face of its tread is left unprovided for. It may not be necessary to employ as many of the devices, or in some cases it might be preferred. to have more of them;

and I leave it to the manufacturer whetherone or both of'the traction. wheels shall be thus provided I do not wish to be limited to the details.
